Chapter 109: Gigantomachia unleashed
Meanwhile at a hospital, All Might wakes up to see Celia, Sam, Tyler, Audrey, and Nelson relieved to see him awake as they hug him. All Might then get up with a headache before asking what happened to him, which caused Celia to tell him that he risked one for all to kill All for one once and for all. Audrey then looks out the window while her siblings ask their father questions about his final fight with All for one until Celia ask her what's wrong. Audrey then turns to her family with tears in her eyes before saying that she hopes that Izu doesn't get killed during the war. Meanwhile, back at the war site, the Devil Brats reported Deku's death to their comrades before telling them that All Might killed All for one. Soon, Gigantomachia's hand breaks through the floor as Harima told him to get them to the castle so they can make sure that the age controller machine and the secret weapon aren't destroy during the death match. Gigantomachia then put the remaining leaders, Kurigori, Giran, the Devil Brats, the Eliminator, The Anti- hero Squad, Team Reservoir Dogs, Merlin, and Nomu on his back before rampaging forward to the destroyed castle.
Meanwhile, the same man from Chapter 60 was about to take a sip from his coffee until an earthquake began as Gigantomachia rampaged through the city, destroying buildings and killing innocent citizens who are in the way with Giant Toga hanging on tight to him as her comrades discuss how are they going to avenge All for one since All Might is at the hospital, causing Gadget to say that they already did by killing Deku, which caused his comrades to smack him on the head before saying that they need to kill every hero and take away dust particles of one for all from the monsters that has them. Soon, Gigantomachia roars to tell the villains that they are almost at the castle, causing Nomu to tell everyone his plan to kill the rest of the heroes, including the U.A. League, Peanut Gallery, and their associates, which caused everyone to initially hesitates before agreeing with Nomu's plan. Meanwhile, the Peanut Gallery and their associates mourn over Deku's death as they comfort each other next to Izenko's grave until Igenium 4 say that on the bright side, Deku will finally reunite with his father. Suddenly, an earthquake began as Mei uses her quirk to see the Warcraft of Doom approaching them as Gigantomachia run over Special and Deku's old house, causing the kids to become furious and told the villains that they had some nerve coming to them after killing Deku. The villains then glare at the kids until Toga told her comrades that the Devil Brats have some unfinished business to do, which caused her comrades to get off her while the Peanut Gallery and their associates prepares for a fight. Kacchan then told everyone that this is the day the villains regrets killing their brother from another mother, causing everyone to agree.
After the Devil Brats got off Gigantomachia, Destro told Gigantomachia to start burying, causing him to do what he was told. Spinner then ask the Peanut Gallery if they're ready to fight to the death, just like All Might and All for one did, causing the Peanut Gallery to confirm that they're ready. Suddenly, Uravity rush toward the brats screaming for Deku, which caused an epic all out brawl to begin at the backyard. Soon, Giant Toga transformed into Giant Deku to use his quirk against the Peanut Gallery and their associates. However, the team remember all their training from internships under mentors, to Eraserhead at the U.A. Stadium, which gives them an extreme advantage against Toga before Eternatus blast her with Dynamax cannon. Toga then fell into a pond that Deku likes to be at, causing most of the water to flood the backyard before getting up and try to attack Team Peanut Gallery, with help from Gadget and Tomura as they use their MMA skills. Meanwhile, Destro, Harima and the rest of the villains ran down the halls of the destroyed laboratory until they found the age controller machine and the secret weapon unharmed. Red then gets an idea and told everyone that they need to de age the Peanut Gallery and their associates out of existence before they can use the secret weapon. Everyone then agrees before heading out to help the Devil Brats defeat the Peanut Gallery once and for all.
